BB1/4-U - 1/4 in Tube x 10-32UNF Nickel-Plated Brass Branch Swivel Tee

The Pneuforce BB1/4-U is an all-metal nickel-plated brass branch swivel tee for 1/4 in outside-diameter tubing and a 10-32UNF connection. Its branch tee layout helps connect pneumatic or vacuum tubing to the correct type of equipment port.

The fitting includes a positive Click-Click grip collar release feature, providing audible and tactile feedback when the collar is depressed during tube removal.

Industrial Nickel-Plated Brass Fitting

This B-Series all-metal fitting is intended for applications where plastic-bodied fittings may not be preferred. Nickel-plated brass provides excellent mechanical strength, corrosion resistance and long service life in demanding pneumatic and vacuum installations.

Typical Applications

  • Branching pneumatic tube circuits near valve manifolds and cylinder ports
  • Routing control air to multiple pneumatic devices
  • Distributing vacuum lines to automation tooling
  • Machine maintenance where the threaded branch position matters

Fitting Function

A branch tee routes two tubing lines from a threaded machine connection. Check the branch orientation and available installation space as well as the tube and thread sizes.

Installation Note: Cut tubing squarely and push the tube fully into the fitting before pressurizing or applying vacuum. To remove tubing, depress the grip collar; the Click-Click release feedback helps confirm the collar has been disengaged for tube removal. Always confirm tubing compatibility for pressure, temperature and media.

Selecting and Installing This Fitting

For BB1/4-U, match the specified 1/4 in tubing outside diameter and 10-32UNF mating thread. Do not rely on approximate inch/metric equivalence without checking tubing tolerances. Cut the tubing squarely, insert it fully and leave access to the release collar. Check actual tubing pressure and temperature limits, which may be lower than the metal fitting limits.

Frequently Asked Questions

What does a branch tee do in a pneumatic circuit?

A branch tee introduces a connection to a main line or machine port while routing tubing to two locations. It is useful for distributing compressed air or vacuum near equipment.

How is a branch tee different from a run tee?

Branch and run tees position the threaded connection differently relative to the two tubing outlets. Select the geometry that best matches the orientation of the machine port and tube runs.

Which sizes are required for this branch tee?

BB1/4-U is specified for 1/4 in outside-diameter tubing and a 10-32UNF port connection. Both tubing outlets use the stated tube size unless the product is specifically identified as reducing.

What is important when routing two tubes from one tee?

Make sure each line is sized for the required flow, leave space to operate the release collars and avoid sharp bends or mechanical loads on the threaded port.

Is this fitting suitable for compressed air and vacuum?

The published all-metal B-Series range is specified for compressed air and vacuum service, subject to compatible tubing, proper sealing and the limits of the assembled system. Other fluids need separate compatibility confirmation.

What are the pressure and temperature limits?

The published fitting-family limits extend from full vacuum to 176 psi (12 bar, as listed for the fitting family), with a fitting temperature range of -40 to +248 °F (-40 to +120 °C). Actual system limits also depend on tubing, seals and installation; do not treat these as fluid-compatibility certifications.
